Apache won't start!!!

Need help here. I'm new to whm, everything was working fine until of late. It seems that apache (although started) will not show anything at all. I'm only able to get to my WHM via the IP address and in there I see the following error message.

Unable to obtain apache version information. Your apache server at XX.XXX.XXX.XXX may be down, or unreachable.

If you are running your own nameservers, then the lynx command will work just fine even if the name has not propagated.

From a remote machine do

nslookup yourdomain.com and check the IP that comes back and compare it to the IP of the server. If they do not match, you either have the nameservers wrong at the registrar, or it simply has not propagated to your ISP yet.
